If you’re reading this blog post, you probably got one of the PDX KBC (Portland Keyboard Club) badges I designed, either at a PDXKBC meetup, SMKmeetup, or at DEF CON. This blog post will go over the materials and tools you need to build the badge, as well as how to flash the firmware and put it together! Bill of Materials Badge and Case PCBs (free!) 4x M3 10+6mm Brass Male-Female Spacers, 4x M3 6mm Screws, 4x M3 Nuts (I bought a kit off eBay for $7.

2019 Robotics Season

The robotics season in finally over! Or rather, the off-season is beginning. This was my last year as a student on the team, so it’s bittersweet. The Season Wilsonville Our first district event was Wilsonville, which was a really great start for us. We were alliance captains and made it to quarterfinals. Our main issue at that event was reliability. Our robot CAN bus was soldered together, so when we figured out that a motor controller had failed before a match we had to cut the CAN, swap the motor controller out, twist the CAN wires back together, and cross our fingers.


One of my favorite scenes from WarGames is after Joshua guesses the launch code and then decides “the winning move is not to play”. I decided to make a fun Go program that guesses the launch code and then interacts with the user as Falken does in the movie. You can find it here. I think the way it simulates guessing the launch code is actually really great as it’s very similar looking to the movie.

BSides PDX Update

BSides PDX was a blast, as expected. My team (@sectribe) ended up ranked 3 out of 26 on the scoreboard. I was the first person to solve the web-100 and web-200 challenge, and the third to solve the web-300. The web-300 was some pretty standard SQL injection, the web-200 was a padding oracle attack on an encrypted cookie, and the web-100 was URL knocking. Out of all of them, the web-100 frustrated me the most.

BSides PDX

I’ll be at BSidesPDX this weekend, for my second year. I’m going to be participating on the sectribe capture-the-flag team with @swordofomen, and some other infosec peeps. I’m gonna focus on web exploits, reverse engineering, and possibly take a crack at the OSINT section. I’m also looking forward to the Hardware Implant Panel talk, given by Kim Zetter, Joe Grand, Joe FitzPatrick, @__MG__, @r00tkillah, Mickey Shkatov and Jason Meltzer.


Peregrine is a scouting app I developed 2018-2019 with Caleb Eby and Brendan Burkhart. Brendan and Caleb kicked off the project, choosing a stack of Go, SQLite, and React. When I joined the team, about a week into development, I jumped straight into the project. I already loved Go, and now there was a chance for me to create something useful with it, with some awesome people! I started working on it the very night I was introduced to it, without a solid grasp on what scouting even was, to be honest.


Software Engineer at Billups with a passion for building maintainable and performant web services with Go. I’m also a mentor for the Pigmice, my old high school FIRST robotics team. I think high school robotics is one of the greatest things any high schooler can do for their future. I help Brian Mock out with organizing the Portland Keyboard Club, and love designing and building keyboards. My other hobbies outside of programming, FRC, and keyboards, would be working on my car, skiing, and listening to music.
